Still the same price..... but surly equally important than is 'When will the motorway sticker become transferable between cars registered to the same license plates'?

Never, in its current form. It's illegal to transfer the sticker from one windscreen to another. But an obvious solution would be to develop a sticker than can't be removed in one piece (actually, this is *theoretically* the case with the current vignette) and have people affix it to the front numberplate. It could still be checked in the usual way at border crossings and police checks and would be much more convenient for motorbikes (where of course it would go on the sole (rear) numberplate). Currently, the vignette is supposed to be stuck "somewhere accessible" on bikes. I just keep mine loose in a lockable compartment on the bike — there isn't anywhere appropriate for the CH sticker, let alone the motorway vignette.

The easiest way by far, would be to include the fee in the number plate tax, you could even reduce it by 25% as there would be no more design/printing/distribution/admin/accounting fees to be taken into account.

People entering with foreign plates would have to buy a vignette valid for 30 days or 1 year on entering at customs point.

Sure some people don't use the highways and shouldn't have to buy one, it's a democracy, majority rules and the majority, by far, use the highways or have their preoducts delivered to the local Migros/Coop by truck/highway.
